Brighton based sculptor and model maker Kyle Bean has installed sculptures in five windows of the London Selfridges department store that show striking examples of the law of conservation of mass.

For a little science refresh, the law states that mass in a closed system will remain constant over time or in balance. Each of the installations consists of two like objects suspended from a scale. The objects have either been altered or deconstructed to show that the difference in form doesn’t translate to a difference in weight.

While cleverly illustrating a scientific principle, they also offer an underlying comment on consumerism. The installations are on view through September 1st 2010.
